I understand what you are saying. Once you start mod'n a car you start sacrifycing reliabilty.

 

get it!!! not too many 650 s2ks out there
your car will be unique and fast!
but you will put good money into it though
good luck!

 

An S2000 that pulls 10s is rare enough....but one that is reliable and streetable? HA! That's just ridiculous. Sorry, but it ain't gonna happen. I have a very unstreetable (but reliable) S2000 and it's nowhere near pulling 10s (not that's what my goal has been).

I have an uber-reliable Evo, too.

But I have to ask....if 1/4 mile times are your goal, why the hell are you considering either of these cars? Why not just buy something that was just meant to go fast in a straight line? Mustang, Camaro, Vette, ZX-10, Hayabusa....

 

Thanks for your input.

What times are you running? Why is your car very unstreetable?

Cant you have a 10 or 11 second car that has two setups (or tunes)? One for street and one for the strip? I am far from being an expert here, but it would seem to me that you can run low boost on the street, while cranking it to the sky for the track.

I wouldn't be getting the car solely for drag racing. My intention is to also auto-x the car, like I have been doing with my Civic.

Thanks again for your comments.

 

Well, one reason that doesn't work as well as it sounds is the turbo sizing for running 10's may not work so well when you "turn down the boost." Then there is the hard-core clutch action, not so hot in traffic. A straight-line high-limit differential might turn funky on the street. And riding around on drag radials is not what I call streetable (though you can swap 'em out fast enough).

Streetable 10's is a rare thing in any car but seems a lot more common in cars that at least start in the 12's.

I suppose a three-plus stage nitrous kit would get you 10's (once or twice per bottle) and may be streetable when turned off...

 

Thanks for your comments.

I have an Exedy Hyper Single (Stage 3) in my Civic right now. It is meant more for race and can be a pain to drive in traffic, but it is a welcomed sacrifice. Is the rear diff from Diff Tech only meant for drag racing? Would it not perform well in autocrossing? If this is the case then I need to rethink my approach because autocrossing is more important to me then drag racing.

What kind of whp do you figure you need to have a 10 second S? The Full-Race Stage 3 turbo kit will produce at least 650whp (with built internals). Understanding that traction becomes the greatest challenge, power would seem to be the least.

 

BTW guys...I am far from being an expert on this subject and am not trying to act like a know-it-all. Please do not take any offense to my statements and forgive my ignorance.

 

If you're willing to spend $15k to $20k to do it, then go for it. But, it's not really the S2000's forte. Of course, by the time you're done with it, there won't be any S2000 left in it.

 

 

Your goals + S2000 = likely not possible. 650whp + big turbo = not an autoX monster, you'll have a hard time having one thats "reliable" depending on your definition of reliable. With the amount of money your going to have to spend, and trouble you might have to go through, I agree with the above statement, American Muscle is your answer.

You can pick up a used LS1 for cheap and make it VERY fast, with gobs of low end torque that will go fast in the straights and pretty decent in the curves. I would also suggest a used C5 or if you can a C6. Even though they use old korean made leaf springs, they handle very well. If you REALLY want a monster... C6 Z06, They make about 440/410 stock, and Ive just seen with longtube headers, make 480/460
